ROTARY PUMP.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed January 30, 1919. Serial N 0. 274,094.

To all whom it may concern:

Be it known that I, J OSEPI-I WISNIEWSKIZ a citizen of Poland, residing at New Acme, 1n the county of Sheridan and State of WVyoming, have invented certain new and useful Improvements in Rotary Pumps, of which the following is a specification.

The invention provides a pump which 1s automatic in operation and designed for use in connection with a flowing stream to be operated by the current for elevating a portion of the water and delivering the same at the required point of use.

The invention provides a pump embodying a stator and a rotor, the stator comprising a cylinder or casing and the rotor embodyinga piston arranged to operate 1n the annular space of the stator and provided with blades which receive the force of the flowing water and impart movement through the rotor.

The drawings illustrate a preferred em bodiment of the invention, however, it 1s to be understood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention as claimed hereinafter.

In the accompanying drawings Figure 1 is a top plan view of a rotary pump embodying the invention.

Fig. 2 is a side view thereof.

Fig. 3 is a view of the pump as seen from the underside.

Fig. 4; is a sectional detail on the line H of Fig. 1 looking to the left as indicated by the'arrow.

Fig. 5 is a sectional detail on the line 5-5 of Fig. 10.

Fig. 6 is a horizontal section on the lme 6-6 of Fig. 5.

Fig. 7 is a vertical transverse section on the line 7-7 of Fig. 5.

Fig. 8 is a sectional detail on the line 88 of Fig. 4.

Fig. 9 is a sectional detail of a modified form of stator showing the portion of the rotor in position.

Fig. 10 is a detail view of a portion of the stator showing the piston of the rotor.

Fig. 11 is a sectional detail on the line l1-11 of Fig. 10.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The rotor and the stator are of annular form and may be of any desired construction withinthe purview of the invention. The stator comprises similar or complementary parts 1 and 2 which are of annular formation and have their middle portions outwardly deflected to form an annular space 3 which constitutes the cylinder or casing of the pump. The parts 1 and 2 are adapted to be connected in any manner by suitable fastenings 4:. The flanges or edge portions of the members 1 and 2 at one side of the annular space 3 are spaced apart and their opposing faces are formed with matching grooves 5 to receive an enlarged portion 6 of the rotor. A bar or supporting member 7 is secured to the stator and serves as means for securing the pump in the required position. Keepers 8 are secured to the bar or supporting member 7 and are adapted to receive poles or beams 9 by means i of which the pump is retained in place in the stream or other flowing water. The poles or beams 9 may be anchored in the banks of the creek or stream to retain the pump in position. A vertical shaft 10 is mounted in the spaced edge portions of the parts 1 and 2. T he blades 13 are hingedly connected to the rotor as indicated at 1 1. The hinged connections 1a may be of any type to admit of the blades having a feathering movement so as. to present a maximum surface to receive the action of the flowing water and a minimum surface to the resistance of the current. Stops 15 carried by the blades 14; are adapted to hold said blades in position to receive the full force of the flowing water so as to impart a rotary movement to the rotor. A pistoni16 carried by the rotor is disposed to operate in the annular space or cylinder 3 of the stator. The shaft 10 is provided with a hub 17 in which the inner ends of the blades 18 are journaled.

At a suitable point in its circumferential length the stator is provided with a chamber 18 which opens into the cylinder, the annular space 3 and from which extends a discharge pipe 19. At one side of the chamber 18 the stator is provided with a plurality of inlets 20 for the entrance of water into the cylinder or annular space 8. A gate 21 is disposed between the inlet 20 and the outlet 19 and is movable across the cylinder or annular space 3. The gate 21 is mounted in a casing 22 which constitutes a portion of the chamber 18. The gate 21 is normally held closed by means of contractile springs 23 which are attached to lateral extensions at the upper end of the gate and to projections of the casing. A lever 24; mounted between its ends is connected at one end to the gate 21 and its opposite end is free and adapted to be engaged by means of a lever 25 mounted upon the stator and having one end projeoting into the path of a trip 26 carried by the rotor. As shown most clearly in Fig. 1 the lever 25 has a lateral extension 27 which is notched to receive the lever 24;. A spring 28 cooperateswith the lever to hold it in a given position that is, with its lower end in the path of the trip 26.

In the operation of the invention the pump is disposed in a stream or current of water and is made secure in any manner as by means of the parts 9. The flowing water acting upon the blades 13 imparts a rotary movement to the rotor which causes the piston 16 to travel in the cylinder or annular space 8. It is assumed that the piston 16 has just passed the gate 21 and the latter is closed. As the piston travels in the cylinder 3 it draws water into the cylinder 3 through the inlets 20 and when the rotor makes a complete revolution and just prior to reaching the gate 21' the trip 26 actuates the lever 25 which in turn operates the lever 24 and elevates the gate to admit of the piston'passing thereby. 'The cylinder is now filledwith water and during the next revolution of the rotor the water previously drawn into the cylinder or annular space 8 is subjected to a compressive force and is expelled from the cylinder through the chamber 18 and discharge'pipe 19 and delivered at the required point of use. During the second revolution of the. rotor water is drawn into the cylinder at the same time that the water previously drawn therein is discharged. After the pump has started, its operation is continuous since it simultaneously draws in a supply of water and dis charges water as will be readily understood. As indicated in Figs. 7 and 9 rings 29 are fitted into the spaced portions of the members l and 2 and secured therein by suitable fastenings 80. This makes provision for ready removal or insertion of the rotor without requiring the separation of the parts 1 and 2. This is of advantage as it admits of the rotor being removed and replaced without disturbing the stator when the pump is in position.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims. 7

Having thus fully described my inven tion, What I claim as new and desire to secure by Letters Patent is 1. A rotary pump, comprising a stator embodying complementary inner and outer annular members having intermediate portions oppositely deflected to form a cylinder and having portions at one side of the cylinder spaced apart, an annular rotor having a portion filling the space at one side of the cylinder, a piston carried by the rotor and operable in the cylinder and blades connected with the rotor.
